Spinner II, The Principle
7
Barrier Filtration

• Removes Particles By Size
• Fine Filtration Requires
• Larger or More Filters
• Frequent Changing

8
Centrifugal Cleaning

• Removes Particles By Weight
• Less Than One Micron
• No Bypassing or Channeling

Principles of Centrifuging
- The centrifuge is a bypass filter - Processes
approximately 10 of lube oil through the
system - Ideal operating pressures 2-7 bar -
Rotor speeds in excess of 10,000 rpm (depending
on application)

Centrifugal Oil Cleaner Installation
Considerations
Note For efficient centrifugal cleaning -

• High pressure hot oil is desirable.

• Unrestricted drain.

Spinner II, The Benefit
13
Spinner II Advantage

• Extended Oil Life

Condemnation Limit

• Extended Engine/Component Life

14
Extended Engine Life

• Full-flow element filters guard against larger
  particles that might cause a catastrophic engine
  failure.
• Bypass filters capture the smaller particles that
  are responsible for long-term engine wear.

• 50 ............1.5 microns
• 75 ............2.1 microns
• 98 ............5.0 microns
• 2 is larger than 5.0 microns

Solids Collected By The Centrifuge Include three
major contaminant types as analyzed by physical
chemistry

Extended Oil-Life

• Dispersant additives keep the soot in suspension.
• Detergent additives prevent the build-up of
  sludge and act as an acid neutralizer.
• Anti-wear additives work by providing a
  sacrificial chemical-to-chemical Barrier.
• The amount of soot suspended in the oil plays a
  significant part in influencing the performance
  of these types of additive.

What Do We Know About Soot In Used Lubricating
Oils ?

• Soot is a by product of the combustion process

• Soot generated in the combustion chamber which
  forms on the cylinder walls travels past the ring
  pack and into the sump lube oil

• Soot forms into what is termed Primary soot
  particles with size range of 20 - 40 nm.

• Primary soot particles agglomerate together to
  form particles whose size range from typically
  0.15 - 0.5 µm.

What Else Do We Know About Soot Agglomerations ?

• The size of soot agglomerations are not dependant
  on additive package makeup.

• It is also reported that an oils additives
  package wear reducing agent becomes less
  effective as soot dispersent additive levels
  increase.

• It is believed that Oxygen and Hydrogen on the
  surface of soot may act as a catalyst for the
  formation of organic acids which are know to
  attack bearings.

What Else Do We Know About Soot Agglomerations ?

• Many reports, such as Sato et al (1999), suggest
  that there is a direct linear correlation between
  wear and Soot concentration. The higher the
  concentration of Soot the higher the level of
  wear observed.

• The trend of lubricating oil manufactures today
  is to try and extend oil life by holding higher
  concentrations of contaminant in suspension in
  the oil (typically up to 10).

What Else Do We Know About Soot Generated Wear ?

• It has been reported that contaminant particles
  which are of a similar size to that of the oil
  film thickness generate most wear.

Wear Rate (cm3/hr)

• Since the trend in oil viscosity is downward (for
  reasons of fuel economy), this also reduces the
  oil film thickness, therefore reducing the
  critical contaminant size.
